|Abstract:||MediaQ is a novel online media management system to collect, organize, share, and search mobile multimedia con- tents using automatically tagged geospatial metadata. User- generated-videos can be uploaded to the MediaQ from users' smart-phones, iPhone and Android, and displayed accurately on a map interface according to their automatically sensed geospatial and other metadata. The MediaQ system pro- vides the following distinct features. First, individual frames of videos (or any meaningful video segments) are automatically annotated by objective metadata which capture four dimensions in the real world: the capture time (when), the camera location and viewing direction (where), several key- words (what) and people (who). We term this data W4- metadata and they are obtained by utilizing camera sensors, geospatial and computer vision techniques. Second, a new approach of collecting multimedia data from the public has been implemented using spatial crowdsourcing, which allows media content to be collected in a coordinated manner for a specific purpose. Lastly, flexible video search features are implemented using W4 metadata, such as directional queries for selecting multimedia with a specific viewing direction. This paper is to present the design of a comprehensive mo- bile multimedia management system, MediaQ, and to share our experience in its implementation. Our extensive real world experimental case studies demonstrate that MediaQ can be an effective and comprehensive solution for various mobile multimedia applications.|
